Abstract (en)

[origin: WO02073520A1] A method for quickly and accurately identifying a digital file (102), specifically one that represents an audio file. The identification can be used for tracking royalty payments to copyright owners. A database stores features of various audio files and a globally unique identifier (GUID) for each file. Advantageously, the method allows a database to be updated in the case of a new audio file by storing its features and generating a new unique identifier for the new file. The file is sampled to generate a fingerprint (106) that is used to determine if the file matched a file stored in the database (108). Advantageously, any label used for the work is automatically updated if it appears to be in error.
